Developing a computational tool to forecast the acute toxicity of biocidal active chemicals and its environmental degradation products for aquatic species is one of the objectives of the European project LIFE-COMBASE. Data on these compounds' toxicity to species in the freshwater/marine and sewage treatment plant compartments have been included in a database. In order to determine whether these substances could be hazardous to aquatic compartments, this study will assess the data that has been gathered. We looked up a number of governmental and scholarly databases. The taxonomic categories, including fish, invertebrates, algae, and sewage treatment plant (STP) microorganisms, were studied using data from 196 biocidal chemicals and 206 environmental metabolites.

The environmental threat posed by oceanic plastic waste, which puts many marine species in peril, is expanding on a global scale. Pinnipeds are extremely prone to becoming entangled, particularly in lost, abandoned, or discarded fishing gear and packaging straps. With the goal of identifying areas of concern and mitigation focus, we explored three international databases to generate a thorough analysis of all recorded pinniped entanglements during the previous 40 years. The majority of entanglement records that have been reported are from North America and Oceania and are concentrated on a small number of widely distributed species (notably, Zalophus californianus and Arctocephalus gazella).
